To determine the density of an irregularly shaped object, a student immersed the object in 21.2 ml
of water in a graduated cylinder causing the level of the water to rise to 27.8 ml. if the object has a
mass of 22.4 grams, what is the density of the object

The density of object is 3.4 g/mL

Explanation:

We are given:

Volume of cylinder without object, = 21.2 mL

Volume of cylinder with object, = 27.8 mL

Volume of object =

To calculate volume of a substance, we use the equation:

We are given:

Mass of object = 22.4 g

Volume of object = 6.6 mL

Putting values in above equation, we get:

Hence, the density of object is 3.4 g/mL
